Quality of high resolution synthesised images: Is there a simple criterion ?

Methods exist which are synthesizing high spatial resolution high spectral content images from a set of low spatial resolution high spectral content images and high spatial resolution low spectral content images. There is a need to quantify the quality of these synthesized images for both the producers and customers of such fused products. Some protocols are discussed. The main concern is on the definition of a parameter characterizing the quality. The requirements on this parameter are discussed. A review of published parameters is made and a new one is proposed. From published works, it is shown that a good quality is achieved when the parameter is less than 3.
